국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

서해안 육상지역을 통과하는 조류의 이동생태를 파악하기 위해, 2014년 7월부터 2015년 6월까지 태안해안국립공원 학암포 지역의 조류상을 조사하였다. 조사 결과 관찰된 조류는 총 14목 30과 88종 23,230개체이며, 평균 조사일당 159.7개체가 관찰되었다. 전체 우점종은 괭이갈매기 Larus crassirostris 21.1%, 되새 Fringilla montifringilla 18.5%, 박새 Parus major 12.7%, 붉은머리오목눈이 Paradoxornis webbianus 8.2%, 노랑턱멧새 Emberiza elegans 5.8% 순이었다. 이동시기인 5월과 10월에는 각각 56종, 조사일당 평균 310.5개체로 가장 많은 종과 개체수가 기록되었다. 종과 개체수가 가장 적은 시기는 여름철인 8월로, 기록된 종 수는 24종이며 조사일당 평균 95개체가 관찰되었다. 종풍부도(R ) 지수는 가장 많은 종이 관찰된 5월에 가장 높았으나, 종다양도(H )와 종균등도(E )는 오히려 이동시기에 낮은 편으로 나타났으며, 이는 일부 상위 우점종의 개체수가 월등히 증가했기 때문인 것으로 판단된다. 환경부, 문화재청, IUCN 등이 지정한 멸종위기 및 법정보호종은 총 9종이 관찰되었다. From July 2014 to Jun 2015, bird survey was conducted in Hakampo, Taeanhaean National Park. A total of 23,230 and 159.7 per day of birds representing 14 orders, 30 families, 88 species were observed. The most abundant species were the Black-tailed Gull Larus crassirostris (21.1%), the Brambling Fringilla montifringilla (18.5%), the Great Tit Parus major (12.7%), the Vinous-throated Parrotbill Paradoxornis webbianus (8.2%), Yellow-throated Bunting Emberiza elegans (5.8%). The number of species and individual was the highest in May and October, respectively, as 56 species and 310.5 individual per day were recorded. According to Korean Ministry of Environment, Cultural Herigage Adinistration of Korea and IUCN Red List, a total of 9 protected species were recorded during the survey.
Neurodevelopmental Outcomes and Brain Volumetric Analysis of Low-Grade Intraventricular Hemorrhage
Seul Gi Park,Hyo Ju Yang,Soo Yeon Lim,Seh Hyun Kim,Seung Han Shin,Ee Kyung Kim,Han Suk Kim 대한신생아학회 2023 Neonatal medicine Vol.30 No.2
Purpose: Extremely preterm infants are prone to brain injury and underdevelopment. Intraventricular hemorrhage (IVH) is the most common cause of brain injury and a significant risk factor for neurodevelopmental delay in preterm infants. Severe IVH is known to have a poor outcome; however, the outcomes of low-grade IVH remain controversial. This study aimed to evaluate neurodevelopmental outcomes and brain segmental volumes of preterm infants with low-grade IVH. Methods: This retrospective cohort study included 109 extremely preterm infants who underwent term equivalent age-magnetic resonance imaging and neurodevelopmental evaluation at a corrected age of 18 to 24 months. We compared infants with and without low-grade IVH. Results: Among the 109 extremely preterm infants, 25 had low-grade IVH and 84 had no IVH. There were no significant differences in the neurodevelopmental outcomes between the low-grade and no IVH groups. In multivariate analysis, low-grade IVH was associated with a smaller medullary volume (adjusted odds ratio, 0.575; 95% confidence interval, 0.346 to 0.957; P=0.034). Conclusion: We found no significant differences in the neurodevelopmental outcomes of extremely preterm infants at a corrected age of 18 to 24 months between those with low-grade IVH and those without IVH. Low-grade IVH was associated with a smaller medullary volume.

This experiment conducted to identify the changes of the response when white-back planthopper (WBPH, Sogatella furcifera), were inoculated in 10 days rice leaves after germination. We confirmed the difference between inoculated and uninfected plants by in the different time period (1day, 1 week, 2 weeks, and 3 weeks after inoculation). Breeding rice and WBPH maintained at 26∼28℃ with 60 % humidity. 3 leaves plants (TN1, Cheongcheong, and Nagdong) were inoculated with 2∼3 instars WBPH. Harvested rice plant samples were completely dried in dark condition and then samples were completely immersed in a solution of methanol for 3 days under darkness. Dissolving in water and then de-fatted three times with hexane. 100 ppm samples were applied to HPLC, eluting with acetonitrile and 0.1 % acetic acid by C18 (5ph column Agilant) and detected at 254 nm. We confirmed the difference of peak using LC/MS/MS (API-2000). The results showed that three weeks from the day of inoculation was increased at the molecular weight 118.1, 264.2 and 364.2.

The White backed planthopper (WBPH), Sogatella furcifera (Horvath) is one of the serious insect pests in rice growing region in Asia. When rice is attacked by the insect it releases secondary metabolites for self-defense. In this study, we identified WBPH-mediated compounds from a cross ‘Cheongcheongbyeo/Nagdongbyeo’ doubled haploid (CNDH). The compounds were located in chromosome. Leaves and stem of CNDH lines were infected by 2∼3 insta of 3 weeks WBPH and samples were extracted by 90% methanol. Extracted compounds were analyzed through HPLC. TLC was used in separating the target compounds. QTL analysis of compound was done using winQTLcart 2.5 program. Chrysoeriol was highly contained in Cheongcheongbyeo. QTL location is found on chromosome by winQTLcart 2.5. QTL analcited with compound7 was detected on chromosome 4, 7 and 12. qFla4 was detected on chromosome 4 in RM280-RM6909 at LOD 3.5 with 30% of variation. qFla7 was detected on chromosome 7 in RM248-RM1134 with LOD 3.0 with 30% of variation. qFla12 was detected on chromosome 12 in RM1226-RM12 with LOD 2.7 with 40% of variation. Cochlioquinone was detected on chromosome8, qFla8 in RM23230-RM3689 with LOD 2.5 with 30% of variation. Chrysoeriol and Cochlioquinone separated to condition of (Chloroform: Methanol:1-Butanol:Water=4:5:6:4). Separated compounds were analyzed by LC/MS and NMR. These results, investigation is being done to ditermine how the secondary metabolites come lead to pathways of genes and its effect on WBPH relation.
